 flat, smooth except on the margin towards the summit, 

 3-5 nerved, sHghtly glaucous beneath ; the upper ones 

 distant and shorter ; Sheaths short, smooth ; Stipules 

 membranous and lacerate, sometimes wanting ; Panicle 

 3-4 inches long, slender, branches solitary or the lowest 

 in pairs, erect, scabrous, simply racemed, rarely subdi- 

 vided ; Spikelets 1-3 near the ends of the branches, 

 pedicelled, 3-5 flowered ; Florets loose, tbmentose at 

 base; Calyx glumes acutish, shorter than a floret, supe- 

 nor one a third longest, 3 nerved, with a membranous 

 margin ; Corol lanceolate, acute, lower valve longest, 5 

 nerved, acutely carinated, keel ciliated with a conspicuous

 half as long as the fruit and without the filiform point.
